Definitions

  • the invention generally concerns a catalyst for chemical applications (e.g., hydrocarbon reforming reactions such as dry or steam reforming of methane).
  • the invention concerns a catalyst that includes a bimetallic (M 1 ⁇ ! 2 ) or trimetallic ( ⁇ 3 ) nanostructure, or oxides thereof, and a hollow zeolite support.
  • the hollow space in the zeolite support includes the bi-metallic (M ⁇ M 2 ) or tri-metallic ( ⁇ 3 ) nanostructure, or oxides thereof.
  • Synthesis gas or "syngas” is a gas mixture that includes carbon monoxide and hydrogen. Syngas is typically used as an intermediary gas to produce a wide range of various products, such as mixed alcohols, hydrogen, ammonia, z-C hydrocarbons, mixed alcohols, Fischer- Tropsch products (e.g., waxes, diesel fuels, olefins, gasoline, or the like), methanol, ethanol, aldehydes, alcohols, dimethoxy ethane, methyl tert-butyl ether, acetic acid, gas-to- liquids, butryaldehyde, or the like. Syngas can also be used as a direct fuel source, such as for internal combustible engines.
  • One of the more common methods of producing syngas is by oxidizing hydrocarbon gases such as methane.
  • hydrocarbon gases such as methane.
  • methane can be carried out using carbon dioxide, water, oxygen, or a combination of such materials.
  • methane can be reformed into syngas by using steam, as shown in the following reaction:
  • the ratio of CO/H 2 obtained in steam reforming process is about 0.33.
  • Such applications include production of aldehydes, alcohols, acetic anhydride, acetic acid, ethers, and ammonia. Therefore, the current solution is to remove excess H 2 from the produced syngas using separation techniques, which can decrease efficiency while simultaneously increasing associated costs.
  • the ratio of CO/H 2 may be increased to about 1.0 by utilizing the dry reforming of methane reaction. In dry reforming of methane, methane is reacted with carbon dioxide or a mixture of carbon dioxide and oxygen as shown in the following equations: CH 4 + C0 2 ⁇ 2CO + 2H 2
  • metals example Pt, Pd, Au, Ag, Ir, Ni, Co, Rh, Ru, La, Mg, Ca, Sr, Ba, Li, Na, K and Mn supported on different metal oxides, for example, A1 2 0 3 , Si0 2 , Zr0 2 , Ti0 2 , Ce0 2 , MgO, ZSM-5, MCM-41, MgAl 2 0 4 have been used reforming processes.
  • noble metal catalysts for C0 2 reforming are based on Ni, Pt, Rh and Ru supported on A1 2 0 3 .
  • the solution of the present invention concerns catalysts having bimetallic or trimetallic nanostructures encapsulated in a hollow zeolite structure that can be used in all types of hydrocarbon reforming reactions.
  • NiCo bimetallic and NiRu bimetallic particles encapsulated in the hollow zeolite structure provide good stability and efficiency in hydrocarbon reforming reactions.
  • trimetallic nanostructures provides another class of catalysts that can be used in these types of reactions.
  • certain combinations of bimetallic and trimetallic nanostructures that are encapsulated in the hollow zeolite structure offer increased catalytic stability and efficiency in producing syngas from either dry or steam reforming reactions of hydrocarbons (e.g., dry or steam reforming of methane).
  • the size of the bimetallic or trimetallic particles are believed to be sufficiently small to prevent coking yet sufficiently large enough to be retained inside the hollow zeolite structure and prevent sintering with other metallic particles.
  • a supported catalyst that can include a bimetallic (M X M 2 ) or trimetallic (M ⁇ M ⁇ M 3 ) nanostructure, or oxides thereof, encapsulated in a hollow zeolite support where M 1 , M 2 , and if present, M 3 , are different, with the proviso that if M 1 is Ni, then M 2 is not Pt in the bimetallic (M X M 2 ) nanostructure.
  • the catalyst can be used to catalyst reformation of hydrocarbons (e.g., C0 2 reformation (dry reformation) or steam reformation of hydrocarbons (e.g., methane).
  • the hydrocarbons can include 1, 2, 3, 4 6, 7, or 8 carbon atoms. In preferred aspects, the hydrocarbon can be methane.
  • the supported catalyst includes at least two metals from Columns 1-16 of the Periodic Table. In a particular instance, when the catalyst includes a bimetallic nanostructure or oxide thereof, M 1 is cobalt (Co) and M 2 is ruthenium (Ru).
  • M 1 is cobalt (Co)
  • M 2 is ruthenium (Ru).
  • Non- limiting examples of trimetallic catalysts can include (M X M 2 M 3 ) nickel/cobalt/ruthenium (Ni/Co/Ru), nickel/cobalt/rhodium (Ni/Co/Rh), nickel/cobalt/platinum (Ni/Co/Pt), nickel/cobalt/cerium Ni/Co/Ce, or any combination thereof.
  • the hollow zeolite support can include an exterior surface and an interior surface that defines and encloses a hollow space within the interior of the support and the bi-metallic (M X M 2 ) or tri-metallic (MVM 3 ) nanostructure, or oxides thereof, can be included in the hollow space.
  • the hollow zeolite support can be made from any zeolite support (e.g., silicate- 1, MFI, FAU, ITH BEA, MOR, LTA, MWW, CHA, MRE, MFE, or a VFI support).
  • MFI is used as the hollow support.
  • the hollow zeolite support is 80 to 99.5 wt.% of the supported catalyst.
  • the hollow space in the zeolite and the bi-metallic (M M 2 ) or tri-metallic (M M 2 M 3 ) nanostructure, or oxides thereof, included in the hollow space can be larger than the average pore size of the pores in the hollow zeolite support.
  • the hollow space can include only one or a plurality of the bimetallic (M l M 2 ) or trimetallic (M M 2 M 3 ) nanostructures, or oxides thereof.
